Step-by-step explanation:
plug the coordinate points into the equations and solve for the remaining variable.
b) (2,3) - 5(2) + b(3) = 16
10 + 3b = 16. 3b= 6. b = 2
(0,8) - 5(0) + 2(8) = 16. 0+ 16 = 16. ☆
a) (4,4) assume based on results you meant y squared. (y^2)
(4)^2 = 4k. 16 = 4k. k = 4
(8)^2 = 4(16). 64 = 64. ☆
Answer:
100.8 minuts
Step-by-step explanation:
12 question = 5 min
1 question = 12/5 min
42 question = (12/5) * 42 min
= 100.8 min
Answer:
6 yds
Step-by-step explanation:
7 + 3 = 10
christine: 7/10ths of ribbon
0.7(20)=14 yds
kaylani: 3/10ths of ribbon
0.3(20)=6 yds
Answer:
33.68
Step-by-step explanation:
The two y values coming from I are equal.
The two x values coming from K are equal.
That's because tangents to a circle from the same external point are equal.
5x + 1 = 6x - 3 Add 3 to both sides
5x + 1 + 3 = 6x -3+3 Combine
5x + 4 = 6x Subtract 5x from both sides.
5x-5x+4=6x- 5x Combine
4 = x
===================
y + 10 = 4y + 2 Subtract y from both sides
y-y+10=4y-y+2 Combine
10 = 3y + 2 Subtract 2 from both sides
10-2=3y+2-2 combine
8 = 3y Divide by 3
8/3 = y
y = 2.67
====================
Now you just put x and y into the parts that make up IK.
IK should come out to 33.68
23.7 is 1/10 the value of 237
